【Netty】TCP粘包和拆包

一、前言　　前面已经基本上讲解完了Netty的主要内容，现在来学习Netty中的一些可能存在的问题，如TCP粘包和拆包。二、粘包和拆包　　对于TCP协议而言，当底层发送消息和接受消息时，都需要考虑TCP的粘包和拆包问题，一个完整的数据包可能会被TCP拆分为多个包发送，或者将多个小的数据包封装成大的数...

Netty解决TCP粘包/拆包的问题

什么是TCP粘包/拆包首先要明确, 粘包问题中的 “包”, 是指应用层的数据包.在TCP的协议头中, 没有如同UDP一样的 “报文长度” 字段,但是有一个序号字段. 站在传输层的角度, TCP是一个一个报文传过来的. 按照序号排好序放在缓冲区中. 站在应用层的角...

Netty的TCP粘包/拆包（源码二）

假设客户端分别发送了两个数据包D1和D2给服务器，由于服务器端一次读取到的字节数是不确定的，所以可能发生四种情况：　　1、服务端分两次读取到了两个独立的数据包，分别是D1和D2，没有粘包和拆包。　　2、服务端一次接收到了两个数据包，D1和D2粘合在一起，被称为TCP粘包。　　3、服务端分两次读...
